Air cooler tube leaking stoppage screwed plug structure

Abstract

The invention relates to an air cooler tube leaking stoppage screwed plug structure and belongs to the technical field of air cooler tube leakage treatment. The air cooler tube leaking stoppage screwed plug structure comprises an air cooler tube and tube boxes at the two ends of the air cooler tube; each tube box comprises a middle inner cavity, an inner wall of the tube box on the inner side, andan outer wall of the tube box on the outer side; the two ends of the air cooler tube are inserted into and penetrated through the inner walls of the tube boxes; conical tapered plugs are inserted inthe ends of the air cooler tube; tube box screwed plugs with screwed plug caps are rotationally arranged at the positions, corresponding to the air cooler tube, of the outer walls of the tube boxes; the centers of the big end faces of the tapered plugs are provided with tapered plug holes; studs are arranged between the tapered plug holes and the inner end faces of the tube box screwed plugs; andattached front nuts and rear nuts are rotationally arranged on the sides, close to the big end faces of the tapered plugs, of the studs. The leaking stoppage structure is good in leaking stoppage effect and high in leaking stoppage speed, and can be fastened again, and the production efficiency is improved; the emergency processing time is greatly shortened, the safety is high; the structure is simple, cost is low, maintenance personnel can complete independently; and the structure is high in universality and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of leakage treatment of tubes of an air cooler, and in particular relates to a plugging structure of tubes of an air cooler. Background technique [0002] In today's increasingly severe environmental protection situation, air coolers, as a new type of energy-saving and environmentally friendly cooling equipment, are increasingly widely used. In order to improve the heat exchange efficiency and save steel, most of the tubes of the air cooler are arranged in an equilateral triangle staggered arrangement, which is densely arranged and the distance between the heat exchange tubes is small. After long-term use, due to medium corrosion, erosion or severe temperature changes when the device is started and shut down, the tube ends of the air cooler tubes are prone to leakage. [0003] In advanced production applications, there are generally three ways to deal with the leakage of air cooler tubes: replacement of tub...
